Carbohydrates that are made up of more than two monosaccharides.


There are two kinds:


Homopolysaccharides: made up of the same monosaccharides, they can be
branched or unbranched.


Heteropolysaccharides: made up of two or more monosaccharide types, they
can be branched or unbranched.

Metabolism: sum of total chemical reactions in an
organism, also the method by which cells extract and
use energy from their environment.


Catabolism: The process by which stored nutrients
and ingested foods are converted to a usable form of
energy. It produces simple products CO2, H2O, NH3,
Metabolism (catabolism
and building blocks such as sugars and fats that are
and anabolism)
used in anabolism.


Anabolism: the process by which simple products and
building blocks of catabolism are used to create
complex biological products that contribute to
organismal growth and development. It also uses the
energy produced in catabolism to do biological work.

Metabolism: undergoing catabolic and anabolic
processes.


Reproduction: cell populations grow via asexual
reproduction.


Mutation: during growth and reproduction, cells
sometimes make mistakes, leading to mutations and
evolution.
Properties of cells
Respond to environment: metabolic pathways
respond to signals, including light, touch, hormones,
and nutrients, that can turn the pathways on or off.


Speed and efficiency: cell operations are highly
specific to maximize targeting and efficiency.


Similar building blocks: most species are very similar
at the cellular level.

What accounts for water's Hydrogen bonding
unique properties?

1) high specific heat, or heat required to raise the
temperature of the unit mass of a given substance by
one degree.
For water to increase in temperature, water molecules
must be made to move faster, or get higher KE, and
doing this requires breaking hydrogen bonds, which
absorbs heat. So, as heat is applied, most of it goes to
breaking the bonds not upregulating KE, thus making
water harder to heat than substances where no bonds
need to be broken.


2) High heat of vaporization, or the amount of heat
needed to turn one g of a liquid into vapor, without a
The unique properties of
temperature rise in the liquid. Important for sweat
water (specific heat, heat
because it ensures that when the liquid evaporates
of vaporization, solubility)
from our skin, the heat required for the transition is
kept in the gas, causing a net cooling effect on the
skin.


3) Unique solubility properties: "like dissolves like".
Water dissolves polar molecules and ions, and can act
as an H-bond donor or receptor


4) Amphoteric, it can act as an acid (donating
electrons) or a base (accepting electrons). The
conjugate acid of water is the hydronium ion, H3O+,
and the conjugate base of water is the hydroxide ion,
OH-.

At 25 degrees C:
Keq for water at 25 Keq= Kw= [OH-][H3O+]= 1*10^-14
degrees C and in pure
water In pure water:
[OH-]=[H3O+]= 1*10^-7

Calculation for pH and pH= -log[H3O+]
pKa pKa= -log(Ka)

Normal blood pH range 7.35-7.45

When non-polar molecules aggregate in the
presence of water, minimizing the entropy decrease
water must go through to order themselves around

the border of the non-polar molecule. Reducing the
